Based on the structure parameter and operating principle of the cooling system of traction converter for CRH3 high-speed electric multiple units (EMUs), a finite element model of air heat exchanger is built. Then the simulation including temperature field and fluid field is done. In order to verify the ability of the cooling system, a thermal capacity test rig for the traction converter is built....
This paper presents an intelligent single neuron (SN) vector control scheme for the linear induction motors (LIM) in order to achieve a high performance. The movement of a linear induction motor (LIM) causes eddy currents in the secondary conductor sheet at the entry and the exit of the primary core. The eddy currents tend to resist sudden flux variation, allowing only gradual change along the air...
